The Rhine gorges, or rather gorges of its sources Vorderrhein and Hinterrhein (“Anterior” and “Posterior” Rhine), are a must-see program. You can see the Viamala Gorge in an hour (or a day if you’d like to hike) and the Ruinaulta Gorge in at least one day (preferably two – from above and below).
In this topic, a map of the region with attractions and a detailed description of the gorges. The region is located in the canton of Graubünden.
